Chapter 173-224-WAC – Wastewater Discharge Permit Fees

What is Chapter 173-224 WAC and why is it being updated?

Chapter 173-224 established a fee system for state waste discharge and National Pollution Discharge Elimination System (NPDES) permits.  The state uses wastewater and stormwater permits as primary tools to protect clean water.


This rule is being amended to update the annual fees for wastewater and stormwater discharge permits.  These permit fees are reviewed and updated every two years as needed to meet the requirements of RCW 90.48.465.

Summary of the rule changes adopted on November 18, 2015

After the completion of a public rulemaking process, Ecology has amended wastewater and stormwater discharge permit fees for state fiscal years 2016 (July 1, 2015 – June 30, 2016) and 2017 (July 1, 2016 – June 30, 2017). Fee categories were also created for Ecology’s new Bridge Washing, In-Water Vessel Deconstruction, and Wineries permits.
